I don't see why the Camel should be on that list.
That's fair enough, and I won't argue with you.
I guess it really comes down to how much individual value you get out of any particular book.
When I think about my own personal experience with Perl, the three things that have had the greatest impact upon my learning curve were:
- getting hold of a copy of the Camel,
- getting hold of a copy of PBP, and
- discovering Perlmonks :)
So if somebody just starting out with Perl were to come to me and ask for some recommendations - that's the list I would give them.
